## Pi Coding Agent

Pi is a terminal-based coding agent built around one idea: the harness should adapt to your workflow, not the other way around. It keeps a deliberately small system prompt and core, which makes it token-efficient and lets you control exactly what lands in the context window. Instructions come from AGENTS.md files, a per-project SYSTEM.md, on-demand skills, reusable prompt templates and extensions that can inject context before each turn.

Instead of shipping every feature, Pi exposes primitives. Sub-agents, plan mode, permission gates, path protection, sandboxing, SSH execution, custom editors and status bars can all be built with extensions, asked for in natural language, or installed from third-party packages on npm and git. MCP is built in, and Codemode lets agents compose tool calls inside a JavaScript sandbox. Session history is stored as a tree, so you can rewind to any earlier message, branch from there, and export or share the whole thing.

Pi runs in four modes: the full interactive TUI, print/JSON mode for scripts and pipelines, an RPC protocol over stdin/stdout for non-Node integrations, and an SDK for embedding it in your own apps. It connects to 15+ providers including Anthropic, OpenAI, Google, Azure, Bedrock, Mistral, Groq, Cerebras, xAI, Hugging Face, OpenRouter and local Ollama, and you can switch models mid-session with a keystroke. Models, packages, changelog and docs all live on the project site.

**Pricing & Plans:** Free and open source (MIT). You only pay your chosen model or API provider; no subscription is required for the agent itself.

- **Extensible harness:** Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git.
- **Context engineering:** AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control.
- **Multi-provider models:** Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session.
- **Four run modes:** Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent.
- **Tree-structured history:** Rewind to any previous message, branch from it, and export to HTML or share the session via a gist URL.

**Strengths:** Open source under MIT with a minimal, readable core; Highly extensible: add or install the features other agents hard-code; Token-efficient thanks to a small system prompt; Broad model support with mid-session switching and local Ollama options

**Limitations:** Deliberately ships without sub-agents, plan mode or permission popups by default; You may need to build or install extensions to get a full-featured experience; Terminal-centric UI has a learning curve if you expect a GUI

## Typelets

Typelets provides shared cloud workspaces designed around live coding interviews and collaborative programming sessions. Instead of a single editor pane, each workspace supports real-time multi-file editing, a shared bash terminal, built-in multi-party video and a problem library with structured rubrics, so interviewers and candidates can work in the same environment without juggling separate tools.

Code execution runs in isolated Firecracker microVMs on Fly.io. Each workspace gets its own sandbox with no network access, hard CPU and memory caps, a temporary scratch area and a short wall-clock limit, and the VM is torn down after a period of inactivity. Supported runtimes include Python 3, Ruby 3.3 with Rails gems, Node JavaScript, TypeScript via tsx, Go, Java 17, C and C++, with more available on request.

Typelets is currently free during its beta phase: unlimited workspaces, interviews, recordings, the full problem library and all language runtimes, with no credit card required. The team has stated that paid plans will be introduced after beta and that current users will be grandfathered onto a generous free tier. Sessions can be recorded and replayed, and workspaces can be shared through a public link so guests can join without creating an account.

**Pricing & Plans:** Free during beta, including unlimited workspaces, interviews, recordings, the problem library and all language runtimes. No credit card required. Paid plans are planned after beta, with existing users grandfathered onto a free tier.

- **Real-time multi-file editing:** Several participants can edit multiple files in the same workspace simultaneously, with a shared terminal running alongside the editor.
- **Sandboxed code execution:** Each workspace runs in its own Firecracker microVM with no network access, hard CPU and memory caps and automatic teardown when idle.
- **Built-in video and recordings:** Multi-party video is embedded in the workspace, and every session can be recorded and replayed later, capturing code edits, terminal output, test results and scores.
- **Problem library with rubrics:** Attach structured interview problems with visible and hidden test cases plus a custom rubric covering correctness, complexity, communication and code quality.
- **Guest sharing without accounts:** Share a public link so candidates or observers can join with a generated identity, in edit or read-only mode, without signing up.

**Strengths:** Genuinely free during beta with unlimited workspaces, interviews and recordings; Multi-file editing, shared terminal and built-in video in one workspace; Firecracker-grade sandboxing isolates every session from the host and the internet; Session recordings and structured rubrics make interview review easier

**Limitations:** Still in beta, so features and stability may change over time; No public API yet and ATS integrations are only partially built; Paid tiers are planned after beta, so long-term pricing is not final
